Description

Technical Field

[0001] The present invention relates to the technical field of U-shaped electric heating tube processing, and particularly relates to a pipe cutting device for U-shaped electric heating tube processing. Background Art

[0002] A U-shaped electric heating tube is a tubular electric heating element designed by bending and forming. Its core structure consists of a high-temperature spring-shaped electric heating wire evenly distributed in a seamless metal tube (such as stainless steel, carbon steel, titanium, copper, etc.) and filled with heat-conducting insulating magnesium oxide powder; during the production process of the U-shaped electric heating tube, operations such as drilling and welding may be required on the pipe. Cutting can remove the excess part to make the size and shape of the pipe more in line with the processing requirements; during the production process of the U-shaped electric heating tube, step punching cutting can achieve automatic cutting, reduce manual intervention, and improve production efficiency; However, the existing technology still has the following problems: The structural specifications of the structure for fixing the pipe on the current pipe cutting device are usually fixed, resulting in the inability to effectively fix the unbent electric heating tube, the U-shaped electric heating tube, or the double-U-shaped electric heating tube. As a result, the electric heating tube is prone to shaking during cutting, reducing the cutting quality, and there are certain limitations. Summary of the Invention

[0003] In view of the deficiencies in the existing technology, the present invention provides a new technical solution for a pipe cutting device for U-shaped electric heating tube processing.

[0004] The object of the present invention is achieved as follows: A pipe cutting device for U-shaped electric heating tube processing includes a workbench, a cutting head, and a carrying mold. The cutting head is arranged to be lifted and lowered at one end of the upper surface of the workbench, and the carrying mold is arranged at one end of the upper surface of the workbench, and the carrying mold is arranged perpendicular to the cutting head. It further includes: A quick positioning mechanism. There are two sets of the quick positioning mechanisms, and the quick positioning mechanism is composed of an upper positioning component and a lower positioning component. A transmission component is arranged between the upper positioning component and the lower positioning component, so that the upper positioning component rotates and approaches the lower positioning component through the transmission component. A positioning cavity is formed on the same side of the upper positioning component and the lower positioning component for positioning the pipe; A linkage mechanism. The linkage mechanism is arranged between the quick positioning mechanism and the cutting head, so that the two sets of quick positioning mechanisms approach or move away from each other through the linkage mechanism.

[0005] Optionally, a material rack is arranged at the center of the upper surface of the workbench for placing the pipe. Both sides of the upper surface of the workbench are slidably installed with carrying slides through the linkage mechanism, and through holes are formed on the same side of the two sets of carrying slides. The material rack passes through the through holes.

[0006] Optionally, the upper positioning member includes an upper positioning plate and multiple groups of flexible steel plates. Multiple groups of limiting holes are formed on one side of the upper positioning plate, and the flexible steel plates are arranged inside the limiting holes. Multiple groups of deformation mechanisms are arranged on the other side of the upper positioning plate, and the deformation mechanisms are arranged in cooperation with the flexible steel plates.

[0007] Optionally, the deformation mechanism includes an extension shell. The inside of the extension shell is communicated with the inside of the limiting hole. Multiple groups of extrusion plates are slidably installed at both ends inside the extension shell, and multiple groups of extrusion plates are slidably installed on the surface of the flexible steel plate.

[0008] Optionally, both the upper positioning plate and the flexible steel plate are arc-shaped. A positioning rod is rotatably installed on the side of the extrusion plate away from the flexible steel plate. Fixing holes are formed at both ends of one side of the extension shell, and one end of the positioning rod passes through the inside of the fixing hole. Fixing mechanisms are arranged at both ends of one side of the extension shell, so that the positioning rod is fixedly arranged on the extension shell through the fixing mechanisms.

[0009] Optionally, the lower positioning member includes a lower positioning plate and a trigger plate. The lower positioning plate is arc-shaped, and the lower positioning plate is rotatably arranged with the upper positioning plate. A groove is formed at the upper end of one side of the bearing slide plate. The lower positioning plate is fixedly installed inside the groove. A through hole corresponding to the trigger plate is formed on the inner arc surface of the lower positioning plate, and the trigger plate is slidably installed inside the through hole. The trigger plate is in transmission connection with the transmission component.

[0010] Optionally, the transmission component includes a transmission rod. The transmission rod is fixedly connected with the trigger plate and is slidably installed inside the through hole. A second gear is meshed and connected to the upper surface of the transmission rod. The second gear is rotatably installed inside the groove, and the second gear is in transmission connection with the upper positioning plate.

[0011] Optionally, the transmission component further includes a first toothed plate. A linkage rod is fixedly installed on one side of the second gear. A third gear is fixedly installed at one end of the linkage rod. A second toothed plate is fixedly installed on one side of the first toothed plate. The third gear is meshed and connected with the second toothed plate. A first gear is fixedly installed at the end of the upper positioning plate, and the first gear is rotatably installed outside the lower positioning plate. The first gear is meshed and connected with the first toothed plate.

[0012] Optionally, the linkage mechanism includes a driving component. Both ends of the outside of the driving component are in transmission connection with dislocation components, and the dislocation components are arranged at the bottom of the bearing slide plate. The second bidirectional lead screw is in transmission connection with the cutting head.

[0013] Optionally, the driving component includes a second bidirectional lead screw. Two groups of the dislocation components are symmetrically sleeved on the outside of the second bidirectional lead screw in a threaded manner. Fourth gears connected to the second bidirectional lead screw are rotatably installed on both sides of the workbench. Shaped plates are arranged at both ends of the top of the cutting head, and the shaped plates are meshed and connected with the fourth gears.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the design of the mutual cooperation of the upper positioning member and the lower positioning member, when the outer surface of the pipe touches the trigger plate, the upper positioning plate can be rotated downward through the transmission member, and the upper surface of the pipe is pressed downward by rotation, so that both the upper surface and the side surface of the pipe can be limited and pressed. Compared with the traditional extrusion method, it is more stable; Secondly, the inner arc surface of the upper positioning plate can also cooperate with the deformation mechanism through the flexible steel plate, so that the flexible steel plate presents different shapes. Thus, when the upper positioning plate rotates close to the double U-shaped electric heating tube, the characteristics of the convex shape of the flexible steel plate can be used to fit the concave place at the folding part of the double U-shaped electric heating tube, so as to further improve the stability of the cutting mechanism for fixing the pipe and expand the applicable range of the cutting mechanism for any pipe; Through the design of the linkage mechanism, the lifting movement of the cutting head can control the quick positioning mechanism to approach and position the pipe through the linkage mechanism. Thus, by using the automatic lifting movement of the cutting head, the pipe can be automatically positioned, further improving the convenience of the pipe fixing mechanism of the cutting mechanism; Secondly, through the mutual cooperation of the driving member and the dislocation member, when the quick positioning mechanism limits and fixes the pipe, the driving member continues to transmit, while the quick positioning mechanism can stay still through the dislocation member, so that the staff does not need to adjust the moving distance of the quick positioning mechanism according to the width of the pipe, further improving the convenience.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 11As shown in the figure, a pipe cutting device for processing U-shaped electric heating tubes includes a workbench 2, a cutting head 3 and a bearing mold 4. The cutting head 3 is arranged to move up and down at one end of the upper surface of the workbench 2, and the bearing mold 4 is arranged at one end of the upper surface of the workbench 2, and the bearing mold 4 is vertically corresponding to the cutting head 3. It further includes: Two sets of quick positioning mechanisms 1. Each quick positioning mechanism 1 is composed of an upper positioning part 101 and a lower positioning part 102. A transmission part 103 is arranged between the upper positioning part 101 and the lower positioning part 102. Thus, the upper positioning part 101 rotates close to the lower positioning part 102 through the transmission part 103. A positioning cavity is formed on the same side of the upper positioning part 101 and the lower positioning part 102 for positioning the pipe. Through the design of the upper positioning part 101 and the lower positioning part 102, the lower positioning part 102 can limit the side of the pipe, and the upper positioning part 101 can limit the upper surface of the pipe by rotating. Moreover, the upper positioning part 101 can use rotation to limit the pipe in a rotating buckle manner. Therefore, the upper positioning part 101 and the lower positioning part 102 can realize two-way positioning and fixing of the pipe, which is more stable than the traditional method using extrusion.

[0030] A linkage mechanism 5 is arranged between the quick positioning mechanism 1 and the cutting head 3. Thus, the two sets of quick positioning mechanisms 1 approach or move away from each other through the linkage mechanism 5.

[0031] As Figures 1 to 11 shown, due to the design that the two sets of quick positioning mechanisms 1 approach or move away from each other through the linkage mechanism 5, and the linkage mechanism 5 is also connected to the cutting head 3. Thus, when the cutting head 3 moves up and down, the quick positioning mechanism 1 can be controlled to slide on the upper surface of the workbench 2 through the linkage mechanism 5. Therefore, the effect of automatically positioning and disassembling the electric heating tube can be realized, further improving the convenience and efficiency of processing and cutting the electric heating tube. Furthermore, a material rack 6 is arranged at the center of the upper surface of the workbench 2 for placing the pipe. Both sides of the upper surface of the workbench 2 are slidably installed with bearing slides 7 through the linkage mechanism 5. Through holes are opened on the same side of the two sets of bearing slides 7, and the material rack 6 is arranged through the through holes. As Figures 1 to 11 shown, through the design that the material rack 6 is arranged through the through holes, the electric heating tube can be first placed on the material rack 6, and then the two sets of quick positioning mechanisms 1 approach each other to limit and fix the electric heating tube. Furthermore, the upper positioning part 101 includes an upper positioning plate 1011 and multiple groups of flexible steel plates 1013. Multiple groups of limiting holes are opened on one side of the upper positioning plate 1011, and the flexible steel plates 1013 are arranged inside the limiting holes. Multiple groups of deformation mechanisms are arranged on the other side of the upper positioning plate 1011, and the deformation mechanisms are arranged in cooperation with the flexible steel plates 1013. As Figures 1 to 11 shown, through the design of multiple groups of limiting holes and multiple groups of flexible steel plates 1013, the shape of the flexible steel plate 1013 is adjusted differently by the deformation mechanism. Through the design of multiple positions, the flexible steel plate 1013 at the corresponding position can be selected to effectively limit and fix the electric heating tube according to the electric heating tube of different lengths. Therefore, the applicability of the quick positioning mechanism 1 can be further improved; Furthermore, the deformation mechanism includes an extension shell 1012. The inside of the extension shell 1012 communicates with the inside of the limiting hole. At both ends inside the extension shell 1012, multiple groups of extrusion plates 1014 are slidably installed, and multiple groups of extrusion plates 1014 are all slidably installed on the surface of the flexible steel plate 1013; As Figures 1 to 11 shown, through the design that multiple groups of extrusion plates 1014 are all slidably installed on the surface of the flexible steel plate 1013, due to the flexible characteristic of the flexible steel plate 1013, the flexible steel plate 1013 can be deformed into a U-shaped or other shapes. When multiple groups of extrusion plates 1014 approach and fit each other, and simultaneously extrude the middle part of the flexible steel plate 1013, the flexible steel plate 1013 can be made into a V-shaped, making it convenient to extend into the groove position at the folding part of the double U-shaped electric heating tube, thereby improving the fixing stability of the double U-shaped electric heating tube; Furthermore, the upper positioning plate 1011 and the flexible steel plate 1013 are both arc-shaped. A positioning rod 1015 is rotatably installed on the side of the extrusion plate 1014 away from the flexible steel plate 1013. Fixing holes are opened at both ends of one side of the extension shell 1012, and one end of the positioning rod 1015 passes through the inside of the fixing hole. Fixing mechanisms are arranged at both ends of one side of the extension shell 1012, so that the positioning rod 1015 is fixedly arranged on the extension shell 1012 through the fixing mechanism; Specifically, as Figures 1 to 11 shown, the above-mentioned fixing mechanism includes a first bidirectional lead screw 10, and the first bidirectional lead screw 10 is rotatably installed at one end of one side of the extension shell 1012. Fixed clamping plates 9 are threadedly sleeved at both ends of the outer side of the first bidirectional lead screw 10. One end of the positioning rod 1015 is located between the two fixed clamping plates 9, and a fastening knob 11 is fixedly installed at one end of the first bidirectional lead screw 10.

[0032] It should be noted that the length of the above-mentioned positioning rod 1015 can always be between the two fixed clamping plates 9 when the flexible steel plate 1013 is deformed into any shape, so as to ensure the stability of the shape of the flexible steel plate 1013.

[0033] Further, the lower positioning member 102 includes a lower positioning plate 1022 and a trigger plate 1021. The lower positioning plate 1022 is arc-shaped, and the lower positioning plate 1022 is rotatably arranged with the upper positioning plate 1011. A groove is formed at the upper end of one side of the bearing slide plate 7, and the lower positioning plate 1022 is fixedly installed inside the groove. A through hole corresponding to the trigger plate 1021 is formed on the inner arc surface of the lower positioning plate 1022, and the trigger plate 1021 is slidably installed in the through hole. The trigger plate 1021 is in transmission connection with the transmission member 103; It should be noted that the upper positioning plate 1011 and the lower positioning plate 1022 are both arc-shaped, so that they can better fit the outer surface of the electric heating tube, thereby further improving the stability of limiting and fixing the electric heating tube.

[0034] It should be noted that the outer surface of the trigger plate 1021 is arc-shaped. When the trigger plate 1021 is completely embedded in the through hole, the outer surface of the trigger plate 1021 can form a unified arc surface with the inner arc surface of the lower positioning plate 1022, thereby increasing the contact area with the outer surface of the electric heating tube.

[0035] Further, the transmission member 103 includes a transmission rod 1034. The transmission rod 1034 is fixedly connected to the trigger plate 1021 and is slidably installed in the through hole. A second gear 1035 is meshed with the upper surface of the transmission rod 1034. The second gear 1035 is rotatably installed in the groove, and the second gear 1035 is in transmission connection with the upper positioning plate 1011; the transmission member 103 further includes a first toothed plate 1031. A linkage rod 1037 is fixedly installed on one side of the second gear 1035. A third gear 1036 is fixedly installed at one end of the linkage rod 1037. A second toothed plate 1033 is fixedly installed on one side of the first toothed plate 1031. The third gear 1036 is meshed with the second toothed plate 1033. A first gear 1032 is fixedly installed at the end of the upper positioning plate 1011, and the first gear 1032 is rotatably installed outside the lower positioning plate 1022. The first gear 1032 is meshed with the first toothed plate 1031; It should be noted that a tooth groove meshed with the second gear 1035 is formed on the outer surface of the transmission rod 1034.

[0036] As Figures 1 to 11 shown, through the design of the transmission rod 1034, when the trigger plate 1021 slides in the through hole, the second gear 1035 is driven to rotate. The second gear 1035 drives the third gear 1036 to rotate through the linkage rod 1037. The third gear 1036 drives the first toothed plate 1031 to move upward through the second toothed plate 1033, so that the first toothed plate 1031 drives the first gear 1032 to rotate. Thus, the first gear 1032 can control the downward rotation of the upper positioning plate 1011, so that the upper positioning plate 1011 can limit and fix the upper surface of the electric heating tube; It should be noted that when the diameter of the electric heating tube is relatively large, and the trigger plate 1021 has not completely entered the through hole, and the upper positioning plate 1011 has already been attached to the upper surface of the electric heating tube, the trigger plate 1021 can drive the lower positioning plate 1022 to limit and fix the outer surface of the electric heating tube by utilizing the design with a certain arc characteristic on its own surface; Therefore, the practicability of the quick positioning mechanism 1 can be further improved.

[0037] Specifically, a stabilizing sleeve 12 is rotatably sleeved on the outer surface of the linkage rod 1037, and the stabilizing sleeve 12 is arranged inside the groove, so as to improve the stability when the second gear 1035 and the third gear 1036 rotate. Secondly, a guiding groove is opened at the lower end inside the groove, and the bottom of the first toothed plate 1031 is slidably installed inside the guiding groove, so as to further improve the stability when controlling the rotation of the upper positioning plate 1011.

[0038] Furthermore, the linkage mechanism 5 includes a driving component 503. Both ends on the outer side of the driving component 503 are drivingly connected with dislocation components 502, and the dislocation components are arranged at the bottom of the carrying slide plate 7. The second bidirectional lead screw 5031 is drivingly connected with the cutting head 3; the driving component 503 includes a second bidirectional lead screw 5031. Two groups of dislocation components 502 are symmetrically threadedly sleeved on the outer side of the second bidirectional lead screw 5031, and fourth gears 5033 connected with the second bidirectional lead screw 5031 are rotatably installed on both sides of the workbench 2. Both ends at the top of the cutting head 3 are provided with special-shaped plates 501, and the special-shaped plates 501 are meshed and connected with the fourth gears 5033; Specifically, as Figures 1 to 11 shown, the above-mentioned dislocation component 502 includes a transmission seat 5021. The transmission seat 5021 is threadedly sleeved on the outer surface of the second bidirectional lead screw 5031, and a dislocation groove is opened on the upper surface of the transmission seat 5021. A connecting plate 5024 is slidably installed inside the dislocation groove. One side of the connecting plate 5024 is fixedly installed with a tightening spring 5022, and one end of the tightening spring 5022 is fixedly installed at one end inside the dislocation groove. The connecting plate 5024 is fixedly connected with the carrying slide plate 7, and a pushing plate 5023 is fixedly installed at one end of the upper surface of the connecting plate 5024, and the carrying slide plate 7 is located between the pushing plate 5023 and the connecting plate 5024; Through the design of the dislocation component 502, when the quick positioning mechanism 1 has already limited and fixed the electric heating tube, and the cutting head 3 is still descending, the transmission seat 5021 can continue to move through the tightening spring 5022, and the tightening spring 5022 can continuously apply pressure to the quick positioning mechanism 1, so as to ensure the stability of the quick positioning mechanism 1 for limiting and fixing the electric heating tube; Secondly, through the dislocation component 502, the two groups of quick positioning mechanisms 1 can limit and fix electric heating tubes with any width, so as to further improve the practicability of the U-shaped electric heating tube cutting mechanism.

[0039] Specifically, as Figures 1 to 11 shown, adjusting rods 5032 are fixedly installed at both ends of the second bidirectional lead screw 5031, and the fourth gear 5033 is rotatably sleeved on the outer surface of the adjusting rod 5032. One end of the outer side of the adjusting rod 5032 is threadedly connected with a fastening nut 8, so that the adjusting rod 5032 is fixedly arranged with the fourth gear 5033 through the fastening nut 8; Through the design of the fastening nut 8 and the adjusting rod 5032, because the compacting spring 5022 has a certain continuous pressure, when an electric heating tube with a small pressure-bearing capacity on the outer surface is needed, the connection between the adjusting rod 5032 and the fourth gear 5033 can be cancelled through the fastening nut 8, and then the second bidirectional lead screw 5031 can be rotated by the adjusting rod 5032 alone to make the second bidirectional lead screw 5031 adjust the initial position of the bearing slide plate 7, so as to avoid the over-large stretching distance of the compacting spring 5022 and damage the electric heating tube with a small pressure-bearing capacity on the outer surface. Therefore, the practicability of the pipe cutting mechanism can be further improved.

[0040] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
